New Visual Demands
In our computer-run society, where an increasing number of jobs require people to sit in front of a computer screen for 8-12 hours a day, a whole new demand has been placed on the eyes, the visual system, and the body. Recent studies show that more than 15 million Americans suffer from eye or vision problems (Computer Vision Syndrome or 'CVS') while using the computer, and that these computer-related problems are on the rise. Most people who suffer from this condition do not even realize they have it.
What is CVS?
Computer vision syndrome (CVS) is characterized by eyestrain associated with using the computer for extended periods of time. Symptoms of CVS include eye irritation, such as dry eye; red, itchy, and watery eyes; fatigue, including heaviness of the eyelids or forehead; and difficulty in focusing the eyes. Other symptoms of CVS are headaches, neck aches, backaches and muscle spasms.
Why does CVS
A personís vision is not suited for staring at a computer screen for many hours. Computer screens are made up of pixels or tiny dots, on which the eye can not lock focus. The computer user must therefore focus and refocus to keep the images sharp. This results in receptive stress of the eye muscles.
Additionally, when you concentrate while performing a near task, such as reading or using the computer , the frequency of your blinking decreases, which causes your eyes to dry out. As a result, your ability to focus diminishes and your vision may blur, which can cause headaches and other painful symptoms.
damage your eyes?
No. There is no clinical evidence that indicates that computers cause long-term vision problems. However, it has been suggested that symptoms of CVS , such as eye irritation, fatigue and difficulty in focusing, occur as a result of external conditions that relate to the computer screen. These conditions may include lack of blinking, poor lighting, improper placement of equipment and supplies, pre-existing eye problems and improper eye care.
Are there over-the-counter treatments available that can alleviate the symptoms of CVS?
Yes. Artificial Tears are available to provide comfort for dry eyes associated with CVS, or dry eye symptoms in general. There are many artificial tears on the market, but in our experience, the two most effective are "Refresh Tears" by Allergan and Bausch & Lomb Computer Eye Drops. These drops provide lubrication and have been shown to relieve tired, strained, and dry eyes. They are designed to be used 3-4 times a day, but are safe enough to use as often as needed.
Can CVS be prevented?
Yes. When working at a computer, there are several easy preventive measures that can reduce eyestrain:
